Team LEO

JUSTIN SILBERT

Justin Silbert brings a wealth of knowledge and experience from DOD and Civilian world.  As CISO of what is now the Walter Reed National Military Medical Center, he managed cyber security as the hospital transitioned into the nation’s most important Joint Military Medical Facility. His expertise focuses on applying sound security practices across a spectrum of systems and environments, from certified medical devices to shared research systems.   Through his work, his goal is to improve the health of organizational leaders, by providing a cyber security program that allows them to sleep better and worry less.

ANDREW HAY

LEOs are legends. They accumulate years of experience filled with noteworthy ideas. Take Andrew Hay for example, with 20 years in the field he held important roles in a number of internationally recognized companies. He is a Co-Founder of LEO and currently serves as the Chief Technology Officer (CTO). The sparks trailblazers leave grab the attention of major media stories and Andrew has been the lead of most. Featured in periodicals like Forbes, Bloomberg, USA Today and several others.

TRACY PALLAS

When we say what we do can’t be taught in a 12-week course, Tracy Pallas is our living example. A tenured hybrid of strategic consulting and cyber experience, Tracy is anything but new to the game. Prior to serving as VP of Channel Sales at Illusive Networks, she held VP roles at Extreme Networks and Palo Alto Networks. Don’t believe us? Ask CRN. CRN’s editorial staff continuously recognizes her innovative achievements year after year. Consistently named one of CRN Magazine’s Top Women in Channels, she was recently recognized as a Channel Chief 2016 honoree.

GLENN SWEENEY

Glenn Sweeney is a trailblazer of Incident Response and Security Operations, particularly for global organizations. Glenn has over 15 years of experience from thinking on his feet. In which time he achieved several security certifications like CISSP, CHFI, GIAC, and GSEC. No wonder this LEO is one of our founders.

BRIAN KELLOGG

Brian thrives on architecting and engineering practically applicable solutions to problems in the enterprise. He has a track record of delivering low cost high impact solutions across multiple IT domains including Cyber Security. Brian is passionate about learning and mastering the topics surrounding any difficulty with which he engages. For Brian, blue teaming is the ultimate enigma as it is a quickly evolving field requiring the continual development of expertise crossing multiple domains. He ardently believes insatiable curiosity fueled creativity guided by experience and expertise is the answer.

DAVID TOMPKINS

David is our mountaineer and growth-master. He’s been to the summit and back multiple times holding leadership and founding roles in some of the industry’s most respected cyber advisory and technology providers. His last trek was with FireEye-Mandiant as an original member of the founding team resulting in one of the biggest IPOs in InfoSec history. Following the acquisition of Mandiant, David jumped in to the real fight going behind enemy lines helping companies and governments battle through some of the greatest breaches in history.

DAVID DEERING

In an industry known primarily for dark rooms and guys in hoodies, it’s easy to think technology is the answer. But after 16 years consulting some of the world’s largest companies on cyber security, David Deering realized product was not the answer. Cyber security requires a unique hybrid of people, processes and technology. And so LEO was born. Prior to founding LEO, David was involved with three other significant startups, two that were acquired and one that went public.

LINDSEY LOCKHART

Lindsey Lockhart is the ace up our sleeve. For the past 10 years she effectively coordinated, managed and executed global campaigns for companies like Entrust, Trend Micro and Armor. As a maven in cyber security public relations, she’s secured coverage in major outlets such as USA Today, The New York Times, FOX Business, MSNBC and Bloomberg. And that’s not a wrap.

Thomas Moore fuses the best of both worlds. His craft is communication and public relations, and his passion is cyber security. At LEO, we look for a unique hybrid of artists and scientists. Thomas’ 20-year career includes PR agency leadership of global technology brands including Trend Micro and NTT DATA. His success speaks for itself. Consistently recognized with industry awards, he still isn’t done. He currently serves as an advisor for LEO and is a strategic communications consultant for Armor.

MARIO CHIOCK

Prior to his current role as Schlumberger Fellow, Mario was the CISO at Schlumberger. He is recognized for his accomplishments and leadership throughout the company and within the community. He’s been listed in the top 25 CISO by ExecRank and won the Information Security Executive “People’s Choice Award” to name a few. But today you can find him on the advisory board of Palo Alto Networks, Onapsis & Qualys.

CLINT BODUNGEN

Trailblazers often leave their mark, but every now and then, some even help build an entire industry. Clint has done just that. With more than twenty years of experience, he is one of the original pioneers of the Industrial Control Systems Cyber Security industry. From the deep technical trenches to the “C-Suite”, few people in the world have been doing it longer. Now, Clint is a frequently requested public speaker, a published author in the iconic “Hacking Exposed” series, and is regarded as one of the industry’s leading experts. At LEO, he is our resident “industrial hacker” and heads up our Industrial Cyber Security Business.

MIKE BURNETT

There’s nothing like learning on the ground floor of an emerging company. Mike Burnett is our jack of most trades. He’s spent more than 15 years inside various security startups, embracing multiple roles in sales, channel development and sales leadership. From IronPort to FireEye and several in between, Mike is a founder and investor of LEO.

ALEX PHILIPS

Alex Philips has decades of cyber experience under his championship belt which he uses to advise LEO. Alex was the first employee at National Oilwell Varco assigned to an IT security project. Talk about being thrown into the deep end. He was quick on his feet and singlehandedly built one of the most recognized cyber security department’s in the country. Alex eventually became National Oilwell Varco’s CISO and now people call him CIO.

RYAN CRUMP

Trailblazers don’t stop after their first successful challenge. They move on to the next. One of our founders, Ryan Crump is the perfect example. For the last 12 years he has helped global companies improve their security posture. From established to emerging technologies, his broad experience makes his wealth of knowledge priceless. For example, as an early hire at OpenDNS, he helped turn the organization into a market leader.

MIKHAIL SUDAKOV

Mikhail is a cybersecurity professional with an enormous passion for the field and thirst for knowledge. In addition to his day job, Mikhail is a professor of cryptology at St. Bonaventure University. A programmer specializing in software security and cryptology, Mikhail always seeks to expand his horizons, hone his skills, and take on new challenges. One day, he hopes to know enough to realize that he knows nothing. Mikhail holds an Offensive Security certification (OSCP) and, although he is a “Russian hacker”, his hat is white and his directive is to protect.
